Review on Watts Premier 560039 UF-3 Ultra Filtration Water Filter Replacement Pack - 5 High Quality Filters for Yearly Use by Beth Martin

I have been using this system for 12 years and ended up buying 9 replacement filters from Revain for a 1 year period. This latest batch, which I installed 10 days after my return window closed, does not filter the water. like the previous filters. This is based on taste (opinion) and TDS (data measured by a digital reader). Revain didn't want to take them back, so I contacted Watts. Watts told me I was out of luck as I didn't buy directly from them they wouldn't support it. $100 is wasted. Literally.
